Revert 00bee6fcd77f, which partially reverted libc++ commit aa7f377c965c

2026-05-01T18:16:18Z

After base 966fb94cb357, this revert is no longer necessary: stdint.h will unconditionally define macros such as `SIZE_MAX`, `UINT64_C`, and others. Submitted by: Nikolas Klauser MFC after: 1 month Reviewed by: imp Differential Revision: https://reviews.freebsd.org/D56746

Partially revert libc++ commit aa7f377c965c, restoring stdint.h

2026-04-25T14:14:11Z

This partially reverts upstream libc++ commit aa7f377c965c: [libc++] Remove libc++'s own stdint.h and locale.h (#107436) These headers are not doing anything beyond the system or compiler provided equivalent headers, so there's no real reason to keep them around. Reducing the number of C headers we provide in libc++ simplifies our header layering and reduces the potential for confusion when headers are layered incorrectly. The problem is that libc++'s own `stdint.h` _does_ do something: it defines `__STDC_LIMIT_MACROS` and `__STDC_CONSTANT_MACROS` before including the system `stdint.h`, causing the latter to expose macros like `SIZE_MAX`, `UINT64_C`, and others. If the `__STDC_LIMIT_MACROS` and `__STDC_CONSTANT_MACROS` macros are not exposed, C++ programs compiled for standards before C++11 can fail with errors due to those macros not being available.
